Thick film organic vapour sensors based on binary mixtures of metal oxides (2003)
Journal Article

Previously, composite sensors incorporating differing proportions of tin dioxide and zinc oxide were reported which exhibited high sensitivity to a range of organic vapours under dry conditions (0% relative humidity, RH). Most importantly, the compos... Read More about Thick film organic vapour sensors based on binary mixtures of metal oxides.

Use of bioluminescent Escherichia coli O157:H7 to study intra-protozoan survival of bacteria within Tetrahymena pyriformis (2003)
Journal Article

A method was developed that enabled real-time monitoring of the uptake and survival of bioluminescent Escherichia coli O157 within the freshwater ciliate Tetrahymena pyriformis. Constitutively bioluminescent E. coli O157 pLITE27 was cocultured with T...

Can the magnocellular pathway read? Evidence from studies of color (2003)
Journal Article

A review of the neurophysiological literature suggests that the magnocellular pathway has adequate spatial-frequency and contrast sensitivity to perceive text under normal contrast conditions (>10%) and also is suppressed by red light. Results from t... Read More about Can the magnocellular pathway read? Evidence from studies of color.

Human mitochondrial branched chain aminotransferase: Structural basis for substrate specificity and role of redox active cysteines (2003)
Presentation / Conference Contribution

Crystal structures of the fold type IV pyridoxal phosphate (PLP)-dependent human mitochondrial branched chain aminotransferase (hBCATm) reaction intermediates have provided a structural explanation for the kinetically determined substrate specificity...

Irrationality, suboptimality, and the evolutionary context (2003)
Journal Article

We propose that a direct analogy can be made between optimal behaviour in animals and rational behaviour in humans, and that lessons learned by the study of the former can be applied to the latter. Furthermore, we suggest that, to understand human de... Read More about Irrationality, suboptimality, and the evolutionary context.

A prototype sensor system for the early detection of microbially linked spoilage in stored wheat grain (2003)
Journal Article

Spencer-Phillips was Co-Investigator, the lead biologist in this HGCA-funded multi-disciplinary work, and co-wrote the paper. The grant was based on his expertise in the microbiology of post-harvest spoilage.

Uptake of 134Cs by four species from the Asteraceae and two varieties from the Chenopodiaceae grown in two types of Chinese soil (2003)
Journal Article

This study investigated the uptake of 134Cs by Lactuca sativa L., Silybum marianum Gaertn., Centaurea cyanus L., Carthamus tinctorius L. from the Asteraceae, and Beta vulgaris L. var. 'Lutiancai' and Beta vulgaris L. var. 'Hongtiancai' from the Cheno...

Syntheses and polymerizations of (E)-2-styrylfurans and an investigation of their electrorheological properties (2003)
Journal Article

Novel furan compounds, which incorporate phenyl rings separated by alkene spacers, have been synthesized. Chemical polymerization of these compounds yielded black brittle powders, suspensions of which were found to exhibit significant electrorheologi...

Selecting plants to minimise radiocaesium in the food chain (2003)
Presentation / Conference Contribution

Caesium (Cs) is an alkali metal with chemical properties similar to potassium (K). It has no known role in plant nutrition and it is not toxic to plants at the micromolar concentrations occurring naturally in soil solutions. However, two radioisotope...

Journal Article

The fission yield of 99Tc from 239Pu and 235U is similar to that of 137Cs or 90Sr and it is therefore an important component of nuclear weapons fall-out, nuclear waste and releases from nuclear facilities. There is particular current interest in 99Tc... Read More about Soil availability, plant uptake and soil to plant transfer of 99Tc - A review.
